Application filed September 13, 1917. Serial No. 191,239.

To all whom it may concern:

Be it known that I, VILLIAME F. FoCHA, a citizen of the United States, residing at Richmond, in the county of Contra Costa and State of California, have invented certain n w and useful Improvements in Hair- Pins, of which the following is a specification.

This invention relates to hair pins, and more particularly to a wire hair pin of that type in .which two prongs are provided, these prongs being of twisted or undulating configuration so as to prevent the pin from being accidentally withdrawn from a persons hair.

One of the main objects of the'invention is to provide a pin of the character stated which may be used for securing a veil or similar article to the wearers hair, the prongs of the pin being so relatively disposed as to be locked when twisted together so as to effectually prevent detachment of the same. A further object is to provide a pin in which the prongs are of a more or less wavy outline so as to prevent withdrawal of the pin from the hair when used in the ordinary manner, these prongs being twisted so as to form oppositely directed elongated spirals, the undulations of the spirals gripping the hair in the same manner as the undulations of the so called crinkly hairpin, with the exception that being oppositelydi'rected. the pin is'more Further objects will appear from the detail description.

in the drawings Figure 1 is a top plan View of a pin con structed in accordance with my invention in locked position, 7 Fig. 2 is a. similar view of the pin in open position,

Fig. 3 is an end view looking at the outer or free ends of the prongs, Fig. 4 isa side view of the pin locked.

Fig. 5 is a similar view open. The pin is formed from a continuous piece of metal or wire bent into an elon-- gated U-shape having the arms or prongs 1 and 2. The prong 1' of the pin is turned outward in an elongated spiral about its axis, as indicated by the arrow in Fig. 2., The prong 2 is also turned inward about its axis in spiral shape as indicated. The prong 1, due to the manner in Which zt is bent, is provided with the alternately d1s posed and oppositely directed depressions 2-, l, 5, and 6, and the corresponding raised portions 3&4, 5, and 6*, respectively. Adjacent its outer or free end, prong l is bent to provide a relatively sharp or sudden rounded portion 7, and a straight locking portion 8 contiguous thereto. The bend 6 and raised portion 6 adjacent the portion 7 is also somewhat sharper than the other bends of the pron 1, for a purpose who later disclosed! he prong 2 is provided with the depressions 9, 10, 11, and 12, and the corresponding swells or raised portions of prong 1 and directed oppositely thereto. This prong is also provided with the sharply bent portion 7 and the contiguous straight locking portion 6 corresponding to the portions 7 and 8 of prong 1 and oppositely directed thereto.

Due to the manner in which the two prongs are bent, by grasping the free ends of the prongs between the thumb and fore- .finger of the right hand, and the upper'end two prongs will he twisted together so as to bring the raised portions or swells of one pronginto the depressions of the other prong. The sharply bent portion or swell 7 of-prong 1, and the corresponding portion 7 of prong 2 fit snugly into each other so as to bring the straight portions 8 and 8 into overlapping locking engagement,

thus effectually preventing unwindin of When it is desired to un ockv the prongs.

the pin, it is grasped in the same manner as above and turned in a clockwise direction so as to untwist the prongs. When open, the pin is well adapted to be used in the ordinary manner for a hair pin, the undulations of the prongs serving to prevent the pin from becoming accidentally disengaged from the hair of the wearer. When locked in the manner described,.the .pin is well adapted to secure a veil or the like to the wearers hair, and it is impossible for it to become accidentally unlocked due to the manner in which the prongs are secured, as-

it is necessary to first move the locking portions 8 and 8 out of engagement before the prongs 1 and 2 can be untwisted or released from each other.

A hair pin constructed in this manner may be quickly and easilyv manufactured at very small cost and, in addition to being Well adapted for use in the ordinary manner as a hair pin, it also provides very simple and efficient means for securing an article to a persons hair.

What I claim is z- A hair pin having two spaced arms, each of said arms being bent outwardly spirally about its axis so as to form a series of undulations, the arms being coiled in the same direction about their axes and the undulations of one arm corresponding with those of the other arm whereby, when the arms of the pin are twisted'together, the unclulations of these members'interengage and cooperate to lnnlr them in this position, each of said arms being further provided, at its free end portion, with a relatively sharply curved portion and a straight locking portion contiguous thereto, the said curved portions being so related as to engage and bring the said straight locking portions into overlapping relation when the arms of the pin are twisted together.

In testimony whereof I aflix my signature in presence of two witnesses.
